Thau’s JavaScript Tutorial

There’s a lot you can do with JavaScript: Images can swap when you move a mouse over them, form elements can influence each other on the fly, and calculations can be made without having to resort to a CGI script. And it works in all major browsers.

This article’s original author, Thau, has been working with JavaScript since its invention, and he created this five-part tutorial to teach you everything you need to know to begin your JavaScript career. The crash course comes complete with many exercises, and you’ll be writing a script by the end of the first lesson.

The series starts off with a look at JavaScript fundamentals, including variables, if-then statements, link events, and image swaps. Keep following along as Thau gets down and dirty with the JavaScript Document Object Model, windows and frames, JavaScript syntax with loops, arrays, and functions, and forms. This all sound like a bunch of gobbledygook? Well, dig in and learn!
